A shared related-records component renders related[] as rows that open the
server-resolved path, with how a derived relation runs. The medication
overview lists them and, in the account's own record, files its condition,
documents and visits; the visit sheet files medications and doses. The
condition page, the document sheet and the dose sheet list what their own
blocks do not already show. A dose's visit named by the form's field counts
as the same relation as the link table.
